The reasons for the poor quality of die-casting molds. Based on the above problems, the editor of Shenzhen mold manufacturer has sorted out the following points: 　　1. When the operator responsible for die-casting mold manufacturing is handed over and transferred, another operator is not Explain the essentials of production to the successor, and never teach your own skills to others for free.

After the new operator comes, you must study and consider yourself, which is one of the reasons for the product failure.　　2. In terms of smelting, the main problem of die-casting molds is that the weight is not measured when feeding, and it is completely dependent on the experience of the operator. Experience is very valuable, but it is also very important to measure and record weight correctly. If there is an error in the feeding meter, the temperature of the molten iron is not high, and the molten iron is oxidized. This is also one of the reasons for the occurrence of various defective products.　　 3. Lack of management of sand for die casting molds. The management of foundry sand is very important, and all die-casting molds are made by molding sand. Nowadays, many factories do not manage molding sand, and molding sand often has poor air permeability. Because of poor air permeability, die casting molds are prone to pores. In addition, the low strength of the molding sand causes the mold to break. More than half of the poor quality of die casting molds are caused by poor casting sand.
